This year, the company is turning to its employees to fund some of that battle. Disney CEO Bob Iger has sent a letter to the company’s employees, asking for them to open their hearts—and their wallets—to the company’s political action committee, DisneyPAC.

In the letter, which was provided to Ars by a Disney employee, Iger tells workers about his company's recent intellectual property victories, including stronger IP protections in the Trans-Pacific Partnership, a Supreme Court victory that destroyed Aereo, and continued vigilance about the "state of copyright law in the digital environment." It also mentions that Disney is seeking an opening to lower the corporate tax rate.

"It just seems insensitive to folks that support the company but don't necessarily support all of its priorities," the source said. "Especially for something like TPP, which I view as particularly controversial. We do have a company position, but there's going to be a wide variety of opinion [within the company]."

The letter concludes with a suggested donation to DisneyPAC. Ars is not publishing the suggested amount in case it is personalized to the source's compensation or position at Disney.
